NVIRO by Walker Environmental

Sudbury’s N-Viro biosolids plant is a centralized wastewater sludge de-watering and stabilization facility producing Class A biosolids at the Sudbury Wastewater treatment plant on Kelly Lake Road. It’s an environmentally responsible and sustainable plant that is safe to all surrounding communities, delivering a long-term, modern approach to wastewater management.

Current Milestone
Onboarding: Members learn about the program, and identify immediate sustainability goals and support needs.
Developing: Members gather data about sustainability performance, set a baseline year, and prepare to report on metrics.
Reporting: Members measure and publicly report on sustainability metrics, and prepare detailed action plans.
Targeting: Members set a public sustainability target and implement action plans.

Total Emissions: An inventory of all sources of greenhouse gas emissions is the total amount of Carbon Dioxide Equivalent produced over the entire business operation, compiled to ISO 14064-1 standard. For comparison, 5.23 Tonnes of CO2 are emitted by the average passenger vehicle in one year.

2016 Total (CO2e): 360.14t  

Scope 1 Emissions: These emissions come from direct release of greenhouse gases, primarily from the consumption of fossil fuels from space heating or vehicle use.

  2016 Scope 1: 271.44t

Scope 2 Emissions: Electricity consumption requires generation. A share of Ontario’s energy grid comes from fossil fuel generation, and this share is reflected in Scope 2, or “energy indirect” emissions.

2016 Scope 2: 87.72t

Scope 3 Emissions: All other indirect emissions are categorized in Scope 3. Standard inventories include scope 3 emissions from solid waste removal, water and waste water usage, but can also include many categories from purchased air and rail travel to employee commuting to work.

2016 Scope 3: 0.98t

Highlights


Opened a newly-built facility in spring 2015 and set a baseline on first full year of operation.

Plans in the works for efficiency upgrades.
